AB  - This report presents a new application for the chitosan-graphene glassy carbon 
      electrode (Ch-G/GCE) system in the determination of the hydroxyflavonoid morin 
      (MR), one of the flavonoids with the highest favorable activity for people, due 
      to its natural properties by square-wave voltammetry (SWV). The anodic peak 
      current for MR was observed at 0.50 V with an increase of 73% compared with the 
      glassy carbon electrode unmodified. The surface areas of Ch-G/GCE, Ch/GCE and GCE 
      evaluated by cyclic voltammetry were 0.140, 0.053 and 0.011 cm(2), respectively. 
      Additionally, an increase greater than 100% compared to the electrode without 
      modification was observed. The detection limit was 0.30 micromol/L for MR, and the 
      relative standard deviations (RSDs) were 1.8% (n = 6). Possible interferences as 
      quercetin, rutin, and applications in real samples were also evaluated with very 
      acceptable results.
